Abstract�� The accuracy and good characteristic in real-time of target threat assessment have important significance to military campaign simulations. The target threat assessment technology based on cloud model was proposed, and the staff gauge clouds were obtained through Bayes revision on the membership clouds gained depending on experts- experience which evaluated on qualitative concepts. Finally the cloud diagram of target threat assessment was obtained through battlefield situation information matching the staff gauge clouds and data disposal, and the assessment was realized. The description of battlefield situation with qualitative concept and membership clouds achieve a good integration in fuzziness and randomicity, which reflect uncertainty when pilots obtain information in air war. An example was given to validate the target threat assessment technology based on cloud model, and the results indicate that threat level assessment can be realized availably by this technology.
